Three identical cylinders with moments of inertia I = ?MR2 are situated in a triangle as shown
Question:
Three identical cylinders with moments of inertia I = ?MR2 are situated in a triangle as shown in Fig. Find the initial downward acceleration of the top cylinder for the following two cases. Which case has a larger acceleration?
(a) There is friction between the bottom two cylinders and the ground (so they roll without slipping), but there is no friction between any of the cylinders.
(b) There is no friction between the bottom two cylinders and the ground, but there is friction between the cylinders (so they don't slip with respect to each other).
Fantastic news! We've Found the answer you've been seeking!
Step by Step Answer:
a Let N be the normal force between the cylinders and let F be the friction force from the ground see Fig Let ax be the initial horizontal acceleratio...View the full answer
